CONVEYER.

Application filed August 23, 1924. Serial No. 733,775.

rllhis invention relates to improvements in c onveyers.

rllbe main objects of this invention are:

First, to provide an improved conveyer which is well adapted lfor the loading and unloadingv ot cars and Which may be readily set iip or adapted tor the particular requirement.

Seconda to provide an improved portable conveyer which may be quickly set up or disassembled.

Third, to provide an improved conveyer which is Well adapted tor handling heavy material such as bags of cement. I

Further, objects and objects pertaining to details and economies of construction and operation Will deinitely appear from the detailed description to follow. h

l accomplish the objects of my invention by the devices andmeans described in the i'ollowingspecification. The invention is clearly defined and pointed out 1n the claims.

A. structure which is a preferred embodiment ot my invention is clearly illustrated in theV accompanying` drawing; forming a part of this application. in which:

Fig. l is a side elevation or the 'main unit and one ot' the supplementary units of mv improved conveyer.

F'Of. ,ll is aV plan view of the structure shone in Fig'. I. the platform of the main unit and a portion of the supplementary unit beine; broken avvay.

lll is an elevation looking from the ri; ito'li Fig. l. one ot the supplementary units being1 shown in position on a truck for transportation, the other supplementary units` being Iindicated as superimposed thereon by dotted lines.

Fie: iV is an enlarged detail side elevation showing' details of the conveyor and the driving' mechanism.

Similar numerals ot reference indicate similar parts in all ot the views.

iteterring` to the drawing, l provide a main unit designated generally by the numeral l and a plurality oi' supplemental units designated generally by the numeral 2. Only one ot the supplemental units is shown as it Will be understood that these supplemental units are duplicates.

The main unit is mounted upon a truck 3 being supported thereon by uprights or standards 4. rlhe platform 5 of the truck 3 is extended at one side ot the main unit to receive the supplemental unit. The main and supplemental units are substantially the same in structure and I use the terms main and supplemental` or supplementary largely as a matter ot convenience in description.

Each unit comprises a pair of side members 6 having hooked coupling members 7 at their ends. The coupling members at both ends of the main unit are arranged facing` upwardly. The coupling members at the inner ends of the supplemental units are arranged facing dovvnvvardly While those at their outer ends are arrangeditacingr upwardly. I

The supplemental units are provided with 8 at their outer ends adapted to be folded for convenience in storing and handling;I the units. rlChese legs when erected support the supplemental units as they are joined together.

Each unit is provided with a carrier comprising a'. pair of shafts 9 extending between the cross members and provided With sprocket Wheels l0. The sprocket Wheels carry the chains ll having cross pieces l2 thereon. The shafts 9 are arranged so that when the units are assembled endY to end one carrier delivers to the adjacent carrier.

Each shaft is provided with a pinion 13, kidler pinions la being` provided at onposite corners of each unit so that when the units are assembled they are provide-d With driving connections and the carriers are driven in the proper direction. To prevent lost motion and relieve the carriers of driving strain I provide each unit with a driving shaft which is disposed longitudinally Within the carrier, these driving' shafts having nears 16 meshintgT with the beveled gears 17 on the shafts 9.

The shafts l5 are supported by the yokelilre members 18, the arms of which are mounted on the shafts 9 to embrace the gears l@ and 17.

The driving' motor 2O is mounted on the truck 3 and is connected to one of the shafts coacting With a gear 26 on the motor shaft.

The shaft "y lil Vith this arrangement of parts heavy loads may be conveyed with comparatively small motors, and the conveyer maybe set up to meet particular conditions or requirements for loading or unloading both ends ofacar.""`

I have illustrated an adaptation Which I have found very satisfactory for the han` dling of cement and heavy objects. Various parts are shown mainly in conventional form as the structural details thereof may begreatly varied. 'I Y'have' not'attenipted to illustrate or d `bc certain modifications or adaptationswhich I contemplate as I blel'eve the disclosure made will enable those skilled in the artto which my invention relates to embody or adapt thesame as may de Having thus described my invention What I claim as new and desireto secure'fby Letters Patent is.:

l. In a conveyer, the combination of a main unit and a plurality `of supplementary units, each comprising side members, a carrier foreach unit comprisingshafts provided with sprocket` Wheels disposed Ybetween the vside members, chains on saidlsproclret Wheels provided with cross pieces, saidY shafts being arrangedV so that 'when said units are assembled end vto'endv with the ends of the side pieces abutting the unit carriers are brought into coacting relation end vto' end, pinions onv the ends of said car# rier shafts, coacting idler pinioiis on the outer end of each unit adaptedy to mesh With the'plnions on said shafts at the inner endsy of 'tlieunits when the `units/are in assembledv relation, driving 'shafts disposed Vlongitudinally of said conveyer units Within said carrier and provided with. bev-Y eled gears at their ends, beveled gears 'on said carrier shafts meshingwith'said gears;

on said transmission shafts, supporting yokes for said driving shafts mounted on said carrier shafts to embrace said beveled gears, a truck on which said main unit is mounted, a motor on said truck, and driv sprocket Wheels provided with cross pieces,

said shafts being arranged so that 1vlien said units are assembled end to end rwith the ends ofthe side pieces abuttingY the unit" carriers are brought into coacting relation end to end, pinions on the ends of said cairier shafts, coacting idler pinions on the outer end of each unit adapted to mesh with the pinioiis on said shafts at the inner ends of theunits When the units are in assembl'ed'relation, driving shafts disposed longitudinally of Vsaid conveyor units within said carrier and provided with beveled gears at their ends, beveled gears on said carrier shaftsmeshing Withsaid gears on said transmission shafts, aiid supporting yokes for saiddriving shafts mounted on said carrier shafts to embrace said beveled gears.

3; In a conveyer, the combination of a main unit and. a lplurality of Asupplementary units, each comprising side members, a carrieiI for each unit comprising shafts, op 3ositely disposed coacting coupling hooks disposed on the under sides of said unit side members to interlock when the side members are brought AintoY abutting relation, pinions on the ends of said carrier shafts, coacting idler'pinions. on the outerl end ofveach unit adaptet lto mesh with the pinions on said shafts at the inner ends of the unitswhen the'un'it's are in assembled relation, driving shafts 'disposed longitudinally of said oonveyer units and provided With beveled gears at their ends, beveled gears'on said carrier shafts meshing With said gears on said transmission shafts, lsupporting yokes forV said driving'4 shafts mounted on said carrier shafts to embrace salidbeveledj gears, a truck on which said main unit is mounted, a motor onsaidtruck, and driving connections for said .motor and one ofthe carrier shaftsof said'ginain unit, said driving connect-ions including a reversing means.

4. 'In-a' conveyer, the combination of. a main unit'and a plurality of supplementary units, each comprising side members, a carrier for'eachunit comprising shafts, oppositely disposed coacting coupling hooks disposed onV the under sides of said unit side members to interlock when the side mem bers are brought into abutting relation, pinionson the ends of said carrier shafts, coacting idler pinions on the outer end of each unit adapted to mesh With the pinioi'is on said .shafts at the inner ends of the units when the units are in assembled relation, driving shafts disposed longitudinally of said conveyer units and provided vWith 'bev' eled gears at their ends, beveled gears on said carrier shafts meshing with said gears on said transmission shafts, and supporting yokes "for said vdriving shafts mounted on ksaid carrier shafts to embrace said beveled gears.

In Witness whereof I have hereunto set my hand.
